Meh, depends on the dyno. Best way to gauge it would be to take it to the strip and look at what the bike is trapping.

[QUOTE=whistle;1321941]I could be wrong but there must be something else here. 40 hp because of a baffle is, well, baffling. Especially coming from LV.

It's not the baffle,( muffler), its the DB killer, a piece of metal that looks like a half dollar coin with just 6 pencils size hole in it. It really restricts the air flow going through the system and plugs up (f-cks-up ) flow. Kind of like shoving a potato into the rear of a exhaust tip. (mean old trick).
Doug saying our bike with just one exhaust pipe, really need it to flow compared to dual piped superbikes.

I too was a little baffled (no pun intended!!) at such a huge loss in power, but in a conversation with Chris (CJS) he mentioned one system in Europo call refer e that uses a restrictor before the muffler that cost him 17HP.
Big difference between 17 and 45!!
But I checked anyway. 5-10mm holes. 392 square mms.
Compared to 2,290 square mm for the pipe. 17% of the area of the pipe.
I couldn't start tuning until I figured it out. You must not [waste your time] tuning a broke engine!!!!
Typically a dB killer is the insert at the rear of the muffler. The LV does have one of those too. I prefer to call it an HP killer!
Once that was out of the picture, I proceeded with the tuning. This is my first Mitsubishi ECU tune, with new software, but it isn't my first ride on the merry-go-'round. (I have used the rest of the tools.)
Once I pulled the cork out of the pipe, it felt like a Ducati instead of a Moto Guzzi. (ouch!!!!)

I don't understand why Greg's is the first, (maybe I'm invisible, or am I not spending enough time self-promoting?) but now that I have the tools and the knowledge....

Wow, that is a massive loss of power. Go with more noise I say!

Wow, you guys can't believe how much better my bike runs now! Way way snappier, and I don't just mean the added horsepower at the top of the chart. What I'm talking about is low rpm 2,500 -3,500 rpm Instant response. No more surging and lurching. Doug got rid of all the weird quirks, no need for adding electronic things to readjusted fueling issues. Do it the correct way! Dyno it!
I believe Doug told me the stock air/ fuel ratio is like 14.3 to 1. The EPA might like it, but we really want it to be, 13.? To 1 for good throttle response . I'll ride it around for a few weeks, then report back with more.
If any you guys reading this are within travel range to Minneapolis MN, Doug will make it worth your while, ( and your Ducati with Love you!)

+1.

You will never know how well your Multi can run untill you get each cylinder properly mapped. Let the pros do it

This is exactly the same experience i had after Tom at Hypertrick did mine.. The before was "ok" but surging and such happened.. After the tune it pulls happily from 2500rpm up to redline.

Thank heaven for tuners who know how to fix an issue the right way the first time!

So you put the Leo Vince on and it lost power .
Did you notice the power loss difference from stock?
Seems you must have...
Did it run that much worse after the Leo Vince was installed ?
So now you MUST run it without the DB Killer ,making it "TOO LOUD"?

Could one alter the DB Killer (make the holes larger ) to quiet it down some? To an "Acceptable " Level . Where the neighbours aren't going to hate you , or you get ear ringing after a longer ride?
Losing that much power after spending that much money is Not the way to go.

Are you it wasn't in the urban or rain mode the first time you took it in?
